I'm a Powerlifter, therefore I train for Powerlifting, not oly-lifting. I think your "advice" can sit this one out vic, your insecurities and issues with Powerlifting are your problem.
I can tell the size of my hamstrings by measuring them. I'm not worried if circumferance is a term exclusive to a perfect circle and not a circular shape, it was to describe the action of measuring the biggest part of my thigh. It measured 22 inches around, hamstring was 6 across. I don't see the reasoning behind challenging a moot point in a condescending way.
I intend to try GHR soon, I have some joint clicking stuff to get checked out soon if they won't bother my knee clicking I intend to do them. Box Squats seem to make my free squat go down for some odd reason or I would try them more. I could try sled dragging.
Any opinions on lunges for Powerlifting?
